The dragonball CPU has a Jtag interface for the initial flashing. I have that Jtag interface and can reflash your unit back to any firmware you want if you really hose it up. This would be a last resort as we have to take the unit apart and remove the foil shield to get access to the jtag interface. We only want to do this if you can not get it fixed by Ectaco under warranty.

I am really working hard to figure out the version of linux they are running. I want to get a copy of the firmware for all the different e-books based on this design. I will then do a comparison of the software to see the similarities and differences over the base os system. I have a message into the chinese manufacturer to find out what linux their system runs.

I am hoping the driver for the buttons and the screen is a system level driver that can be accessed just like the terminal in linux. This would allow us to add our own applications to the system.

M218C+ > basically an M218A++ without the lithium battery (replaced with AA battery compartment), probably with less system memory (32MB??)

M218C > probably the M218C+ leaving out the headphone jack and any mp3/TTS function (Jetbook Lite)

When you try to cross-flash your Aluratek/Jetbook with Chinese firmwares, you can refer to the above. Hope that helps.

No, it didn't help. I just bought a Libre pro. It won't take M218A or A+ and it will complain and says you need M218B. But I have tried almost every 218B versions I can find from Chinese website and from the link someone post here, none of them worked on Libre. Can someone please help to crack Libre pro? Thanks.

Libre has some code that limits you to only flashing with their own firmware. You have to hack around it... perhaps even flash to the jetBook firmware before the Chinese version. But you risk bricking your reader.

No, I can't even flash it to jetbook firmware. Tried so many times. Mine is 1.6h now. I am wondering how people said they flashed their libre to jetbook?

I read a guy said he flashed his jetbook to chinese Yibuoshi 218A+. He didn't say how he did it, as expected.

I also read from this forum, some people here know how to modify the code in the firmware. Can someone please let me know how? thanks.

Is there any place where I can get the older version of jetbook firmware? The current on on Jetbook site can not be flashed to Libre 1.5 or 1.6? thanks.
